1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Introduction: Essential renal bleeding is rare and lacks standardized treatment; organ-preserving options are critical in older patients with impaired renal function. Case Presentation: A woman in her early 80s with atrial fibrillation treated with edoxaban, chronic heart failure, and advanced chronic kidney disease presented with gross hematuria and bladder tamponade. Bleeding was localized to the right renal pelvis and ureter, with no tumor, urolithiasis, vascular malformation, or glomerular disease; essential renal bleeding was diagnosed. Hematuria persisted despite edoxaban discontinuation, red blood cell and plasma transfusions, and carbazochrome sodium sulfonate administration. Isolated factor XIII activity was 22%. Intravenous plasma-derived factor XIII concentrate achieved sustained hemostasis, renal function remained stable, and reduced-dose edoxaban was safely resumed. Hematuria did not recur within 24 months. Conclusion: In this population, factor XIII deficiency may contribute to persistent unilateral hematuria despite normal conventional coagulation tests.
